    摘要： A device bus node associated with an aircraft device has a plurality of communication ports for connecting with a respective bus of an electronic or optoelectronic bus system of a distributed system of an aircraft. The device bus node is configured to receive bus messages from at least one controller bus node of a controller sub-system of the distributed system and perform a self-configuration procedure after that each of its communication ports was connected with a respective different one of the busses of the electronic or optoelectronic bus system, for being fully operational in the distributed system, wherein the self-configuration procedure determines, based on bus messages received at its communication ports, at least part of individual configuration data being associated to the device bus node as part of the distributed system and being needed by the device bus node to enable a processing of a respectively received bus message.

    摘要： Various embodiments of the teachings herein include methods for operating a vehicle. The methods may include: accessing a travel plan identifying an intended destination and a predicted state of the energy store including a predicted value for a parameter of the energy store upon arrival; determining an instantaneous location; determining a predicted value for the first operating parameter based on the location and the travel plan; measuring an instantaneous value for the parameter; calculating a first deviation between the predicted value and the instantaneous value; calculating an expected final value for the parameter upon reaching the intended destination based on the instantaneous value; calculating a second deviation between the predicted final value and the expected final value; indicating to an operator both of the deviations; and executing one or more changes to controls of the drive system in response to at least one of the two deviations.
